What is oceanography?

The fields of mathematics, physics, chemistry, biology, and geology all meet in the discipline of oceanography.

Physical oceanography, chemical oceanography, biological oceanography, and geological oceanography are the four traditionally used terminologies to describe oceanography:

• Physical oceanography is the study of the physical characteristics of the ocean, such as its temperature and density, as well as its motion due to waves, currents, and tides.

• The study of the biogeochemical cycles that alter seawater's composition is known as chemical oceanography.

• The study of biological organisms in the ocean, including their life cycles and food production, such as bacteria, phytoplankton, and zooplankton, as well as the more conventional marine biology focus of fish and marine animals, is referred to as biological oceanography.

• Geological oceanography is the study of the composition, characteristics, and development of ocean basins.

The field of oceanography encompasses more than just these individual branches. Oceanographers utilize a range of instruments to research the water, and many of these investigations span several fields. Ships are used by oceanographers to gather specific water, sediment, and biological samples (Research Vessels). To collect data over time and space scales that a ship cannot, they deploy autonomous sampling equipment like buoys and gliders. Oceanographers can gain a worldwide perspective on some characteristics using remote sensing from aircraft and satellites. Oceanographers can use modeling to examine the past and forecast the state of the ocean in the prospective (e.g circulation, air-sea interactions, sustainability of fisheries, quality of water, etc.).

Oceanographers are able to do a variety of things thanks to the knowledge gained from all of these different types of measurements, including, but not limited to: 

• better predict (using models) changes in weather and climate improve the forecast for hazards, both natural (like hurricanes) and man-made (e.g. oil spills)

• evaluate the effects of contaminants on the ocean's water quality and take steps to protect it in the face of rising human demand (e.g. fisheries, tourism, shipping, offshore oil & gas, offshore wind farms, etc.).

For those interested in studying the ocean and its surroundings, a career in oceanography is the greatest choice. Oceanographers are in high demand because there is a need to understand the many oceans that exist on our planet. The oceanographers research the ocean's waters and how they affect weather, marine life, and other factors.

Oceanographers can operate in a variety of sectors, including the oil business and conservation. Depending on the expertise in this area of study, job responsibilities change.An eligible oceanographer should begin by obtaining a bachelor's degree and any necessary work experience. Jobs are needed because of the necessity to manage water resources and safeguard the environment.

3 Best Bachelor’s Degrees in Oceanography in the US

• North Carolina State University, a prestigious research institution, is situated in Raleigh, the state capital. A Bachelor of Science in Marine Sciences with a focus in Biological Oceanography is given by NCSU's Department of Marine, Earth, and Atmospheric Sciences. The curriculum gives students a solid foundation in the sciences and mathematics related to oceanography. The program's exceptional 6-to-1 student-to-faculty ratio ensures intimate mentorship ties and specialized attention. The department regularly conducts research on a variety of subjects that will be useful to students, including examining biogeochemical cycles, comprehending air-sea interactions, and comprehending the numerous stresses placed on marine ecosystems. The department is a member of the Consortium for Ocean Leadership.

• A Bachelor of Science in Oceanography is offered by the College of the Environment at the University of Washington, which is based in Seattle, Washington. Students complete a series of courses going through complex themes including comprehending the interplay between the seabed and water column and global biogeochemical cycles as part of the degree program, which also includes supporting modules in the sciences and mathematics. The majority of students typically have at least one field experience before the conclusion of their second year. In addition to five separate buildings with numerous rooms for classroom instruction and lab work, UW has two vessels it uses for research and teaching.

• Florida Institute of Technology, based in Melbourne, Florida, provides a Bachelor of Science in Oceanography. The program exposes students to a wide range of subjects, including biology, chemistry, physics, meteorology, geology, and more. Students use these disciplines to study the ocean and other aquatic life forms. Numerous factors make the FIT program excellent, including the low student-to-teacher ratio and the top research labs that are situated on campus and in the surrounding area. FIT features two different marine laboratories, an Underwater Technologies Laboratory, and many other top-notch locations for training in lab and field settings.
